Answer:
According to an energy pyramid model, Producer is expected have the largest biomass in land ecosystems
Explanation:
In a trophic level, the producers possess the largest biomass. With the increasing trophic level, the biomass reduces. Hence, the producers at the base have high biomass.
On terrestrial ecosystem, the producers are the plants and trees and hence the greatest biomass exists in the plants and trees.
Hence, in an energy pyramid model, Producer is expected have the largest biomass in land ecosystems
